To all whom it may concem:

Be it known that I, GEORGE L. Hess, a citizen-of the United States,residing at Denver, in the county of Denver, State of Colorado, haveinvented certain new and useful Improvements in Metallic Apron Intakesand Outlets; and I do hereby declare the following to be a full, clear,and exact description of the inventiqn, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to metallic apron intakes and outlets to be usedin tapping canals employed in mining, irrigation and other forms ofhydraulic engineering.

The object of the invention resides in the provision of a metallic apronintake and outlet of the type referred to which is adapted to lead waterfrom a supply canal to a flume system by means of which latter the wateris distributed over an extensive area; said metallic apron intake andoutlet including an improved structure which will enable same to adjustitself to the varying conditions due to the expansion and contraction ofthe flume with which it is associated, said expansion and contraction ofthe flume arising upon variations of temperature.

A furtherobject of the invention resides in the provision of a metallicintake and outlet of the character referred to which will preventleakage therearound and con sequent destruction of the embankment inwhich the apron is embedded.

A still further object of the invention resides in the provision of ametallic intake and outlet apron which may be easily transported overlong distances, capable of being installed at very little expense, andwhich may be manufactured at small cost.

With the above and other objects in view, the invention consists in, thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claims.

In describing. the invention in detaihref.

erence will be ,had to the accompanying drawings wherein like charactersof reference'denote correspondlng partsin the sev-..

eral views, and in which- Figure 1 is a plan view :of' an. intake andoutlet apron constructed in accordance with the invention with a flumesection attached a comparatively said member.

side edges of the member A are strengthened by means of angle irons 12which extend longitudinally of the member and are secured a ainst tl-.outer face of the latter. The ma or. end'of the member A is alsoreinforced by means of an angle iron 13, which latter is also securedagainst the outer face of the member in any suitable manner. Secured toeach of the angle irons 12 is an anchor rod 14 which extends downwardlyfrom said angle iron 12 and carries at its their adj alower end a crossarm 15, said rod and cross arm constituting an anchor for the apron aswill hereinafter appear. The sections 10 are provided at their minorends with registerlng flanges 16 to which are adapted to be riveted ajoint member 17 for cotiperation with the adjacent end of a flumesection.

B. The member 17 and the end of the flume section B are connectedtogether by a joint of the type described and claimed in my applicationfiled December 10, 1910, and serially numbered 596,674.

In use the member A'is embedded in the enbankment adjacent a canal withits lower portion beneath the level of the water. The anchors secured tothe angle irons 12 are of course buried in the earth and the cavity inwhich the member A is seated is of a shape corresponding to thesuperficial shape of The flume section Bis then attached to the minorends'of the apron in the manner heretofore referred to and other flumesections are then attached in succession as desired. As the water flowsthrough the member A fromthe canal the pressure thereof will always"tend to automatically force the memher A into engagement with thesurrounding outer face of the member A and consequent destruction of theembankment. It also be apparent that the a ron constructed as shown anddescribed will be of an exceedingly flexible type so as to readily givedur ing the expansion and contraction of connectedparts and thus preventcracking or breaking of the'intake and outlet with resultant increaseddurability and prolongation of life,

What is claimed is; I

1. An intake and outlet apron comprising a semi-frusto conical member,longitudinal stiffening bars secured along the sides of said member, atransverse stifi'ening bar secured along the major end of said member,anchors secured to each of said longitudinal stiffening bars, an angularflange formed at the minor end of the member, and a flume joint memberattached to said flange.

2. An intake and outlet a ron comprising a semi-frusto conical mem er,means for anchoring the lateral portions of said member, an angularflange forined at the minor bar secured along the major end of saidmember, anchors secured to each of said longitudinal angle bars, andangular flanges formed at the minor end or each of said plates, saidflanges being dis osed incontinuity, and a flume joint mem er-connectedto said flanges. i v v In testimony whenof, I aflix my signature, inpresence of two witnesses.
